The series debuted in 45th place (8.1 million viewers) and attracted about 7.7 million viewers in weeks two and three. But its ratings nosedived to 5.8 million when it went head-to-head against "American Idol," Eonline.com said.
"Going up against 'American Idol' was a tall task for the show," CBS spokesman Chris Ender said.
The Muncie, Ind.-set series chronicled television actor Erik Estrada; singer La Toya Jackson; "Jackass'" Jason "Wee Man" Acuna; MTV reality veteran Jack Osbourne and former WWE star Trish Harder as they trained to become reserve police officers and then went on patrol with their real police officers.
Despite the show's cancellation, Muncie Mayor Dan Canan said he was pleased how his city and the police department were portrayed.
